Grand Prix :: 2000 - Cooling Fans And AC Compressor Not Working
Cooling Fans and a/c compressor not working-2000 Grand Prix. They both work when I jumper them. Replaced coolant temperature sensor, checked fuses and relays -all good. Not sure what to troubleshoot from here.

I have a 93 pontiac grand am 3300 V6 with auto tranny. My problem is cooling fan starts running as soon as car is started. AC not on or defrost. In turn doesn't allow engine to reach normal operating temp. I have replaced both the ect sensor & gauge sending unit. I've noticed there's a red light with temp symbol in lower left hand corner of instrument panel that stays on & won't allow ac to come on. Also if I unplug fan relay & allow engine to come up to operating temp the light hoes off. Until the engine drops below 200degrees then it'll come on again. It has just the one fan & I have ruled out the fan relay cause I replaced with a new one. Also, looking for wiring diagram for the rest of relays on firewall & as to what they control.

My engine cooling fan came on when I first started the truck, was reading of 2k on torque app, ECT was appx 100* with the EOT a little cooler after about 5-10 minutes things went to normal around 600 rpm. It did not happen anymore during the drive, I was seeing about 192* ECT and 198-200 EOT. I let her set for 2 days and took her to town and the fan was at normal RPM's, Is there any problems or is that normal?
View 9 RepliesMustang :: No AC Cooling As Compressor Was Not On
My daughter has a 02 stang with the 3.8 . the other day she complained that her ac was not cooling so i put my gauges on it and checked the freon. the compressor was on and the low side showed about 35 and high side was about 225. it was cooling good, now today it was not cooling at all and the compressor was not on so i jumped the pressure switch on the dryer and it came on, pulled the jumper and plugged it back in and compressor came back on and started cooling. I might have a bad pressure switch also about the pressures could the orfice tube be getting stopped up. this car must have had ac problems before with the previous owner because someone has wired the ac clutch 12v+ wire to the outlet side of the pressure switch and the 12v- side to a ground screw.
View 1 RepliesGrand Prix :: AC Compressor Not Engaging / Rattling
Last year my a/c worked off and on. so far now its not working at all. Compressor isn't kicking on. i bought a bottle of the EZchill refrigerant to recharge the system. I took the relay out and added 12+ to the pin to kick on the compressor. Even with the compressor running the gauges are in the blue range which is the normal operating range. With the compressor running, the air is cold but when i stick the relay back in the compressor wont kick back on. I tested the relay and its fine. Also the compressor is rattling.

Have a 06 Grand Caravan 3.8L that suddenly quit and would start back up easily enough, but one had to keep foot on the gas to keep it going.
I pulled two codes:
P0123-throttle postion sensor 1 high
P0508-IAC valve sensor circuit low/undercurrent
So far I have removed the IAC and cleaned it with throttle body cleaner, cleaned throttle body out as well with the spray, installed new EGR since it got mangled trying to remove it for cleaning. Removed the TPS connector and with key on, took measurements and I am getting a reference voltage proper ( almost 5 volts). I then back probed the connector once it was plugged back in and again things checked out, the reference lead was varying between .7 and 4.7 volts as I manually moved the throttle plate.
I had switched out the IAC with a used one, from an engine that had been running before being parked, but it made no change.
Note: I have a new TPS but am holding off on changing it until I investigate whether or not it may have a clogged fuel filter causing it to stall at idle speed. Now if can just locate where it is..the sketchy diagrams in my Alldata program are useful.
Grand Prix :: 2004 GTP / AC Compressor Only Works When Jumped?
2004 GTP. I have recently replaced the condenser, drier, compressor......
My issue is that my compressor only works when jumped. I checked the relay and 10 amp fuse located in the engine bay fuse box and both seem fine. I replaced the pressure switch and put a new pressure switch connector on it. I got it to take a full charge by jumping the compressor. It blows very cold when jumped. The outside temperature on the dash is reading correctly.

i have a Echo 2005,140 000 km,AC.Changed antifreeze with a proper mixture(bought from Toyota). Changed the thermostat(from Toyota) as well and flushed the radiator with water at the mechanics garage.The water was going out from the bottom hose on a steady flow. Yesterday drove my daughter back from school, distance around 10 km(5-6 miles around),ambient temp.was about 15 degrees Celsius(around 59F), 3 traffic lights, 4 stops at the last traffic light the fan turned on and worked for 5 sec. I can`t imagine what will happen in the summer when its 40 C(around 104 F). No AC on, no defrost on, water pump its not leaking and its not noisy. I used to have 2000 Echo did pizza deliveries, i ve heard the fan only in very hot weather ,never in such conditions. Same with my Corolla, never heard the fan in such conditions. Actually at the last traffic light the only car with a working fan was mine.
View 5 RepliesSanta FE SM (2001-06) :: No Cooling From AC / Compressor Not Running
03 Santa Fe, 2.7 L engine. No cooling happening. Compressor not running. Jumpered both sides of the triple pressure switch. Jumpering Low/high side resulted in slight increase in engine rpm, Jumpering medium side and something turned on (didn't get a chance to investigate) but still no clutch operation on compressor. Wondering what to try next other than disconnecting and dropping compressor ?? Checked AC relay on the bench and the coil operates and contacts close, so that's good. Also10A fuse before relay contacts is OK.
View 12 RepliesPrius (2004-09) :: AC Compressor And Condenser Cooling Fan Will Not Come On
I have an 05 Prius with 53k miles and the ac just recently stopped working. The blower fan still comes on, but neither the compressor nor condenser cooling fan will come on. I've checked the fuses and relays, and they check out ok. I'm hoping there may be one I missed? It just stopped working with no warning signs. What could be causing this? If the compressor was bad, the condenser fan would still work, right? I'm fearing it's the ac inverter. Do the symptoms match?
View 9 RepliesNissan - Frontier :: AC Compressor Clicking / No Cooling
We have a 2003 Nissan frontier pickup (automatic).The AC recently stopped cooling, but the fan works. It was cooling perfectly great when all of a sudden, it stopped. If we turn the AC on, the compressor (I'm guessing) starts to click and continues to click until turned off. (started to grind under hood). It's not a rattle, definitely a click as if it wants to turn on but can't make the electrical connection. It kind of sounds like when a starter has gone bad and it clicks. Except, it does it repetitively until turned off. This doesn't happen if we turn on the fan but leave the AC off. Does it sound like the compressor went out? How can we troubleshoot it?
View 19 RepliesPrius (Gen 3) :: Battery Cooling Fan Constantly Runs At Every Highway Trip
The past week I have noticed my battery cooling fan running constantly on all highway trips - 20 mile one-way trips going 65-70MPH.
The performance of the battery doesn't seem be degraded, but it seems like the battery is hopping more between charging cycle or whatever you would call it , where you watch the instantaneous MPG on the highway drop down for 10 seconds to 40-50, then back up to 60-70.
The car is a 2011 Prius III. It did not run like this earlier in the summer in the same weather conditions, I would hear the fan maybe once every few weeks in hot 90 degree weather. Now I hear it constantly. This is my first summer owning the Prius so this may be normal, but I wanted to double check with you all if this is a sign of premature traction battery death or something.
Chevrolet - S-10 :: AC Compressor Runs, But The Air Is Not Getting Cool
The A/C is not working in my 2002 S-10. Currently the compressor runs, but the air is not getting cool. I tried adding freon, but it has not worked. The low side pressure is about 50 psi, and would drop a few pounds when the compressor is started, but it drops no further. I have not noticed the compressor cycling while it is on. The can of refrigerant is not empty, but the system does not seem to be taking any more from that can.
Do I just need to add some more coolant from a fresh can, or is something else at work here. Also, probably unrelated, when down shifting it is fairly common for the air to switch from blowing up front to blowing on the defrost.
Silverado :: 1994 Chevy - AC Compressor Engages But No Cooling Really At All
The issue I'm having is the A/C. When I got the truck the A/C was completely freezing. Recently however, the compressor was having issues not engaging and I fixed that by simply plugging the cord to the accumulator thing. . Now the compressor engages, but is not cooling really at all. It is an old truck and the compressor is a little worn from what I see maybe 2mm space when not engaged. I checked the levels of freon/coolant with a gauge and the amount is perfectly fine. Plus there seems to be no leaks.
View 1 RepliesFord :: 2007 F150 - No Cooling Of Air / Air Conditioning Compressor?
2007 Ford F150 half-ton. No cooling of air at the outlet of the ductwork. Freon charge is good, I watched the tech pull the system down and hold it for the prescribed time period. Compressor will not start. I am being told that this means a failed compressor, but I am of the idea that the pressure switch for low pressure must have failed, or the orifice is stopped up. I am also being told that the compressor, evaporator, and orifice tube needs replaced in order to remedy this issue. The counter man at my local parts house cannot find in his computer any pressure switches, kinda making me think that everything is in the unit. In short, if I can avoid buying the compressor, I would like to.

Have an issue with my front air con not working.....
When you start the car there is a rattle/squeaking noise, this sounds like a worn pulley, when you press the air con button to turn it on the noise stops. It does not make any sound changes to the unit/engine to indicate the compressor engages and the is no cooling from the unit.....
Is it a new compressor or is there a common fix for this issue?
